An oil guiding structure for a range hood and a range hood

Abstract

This utility model discloses an oil guiding structure for a range hood and a range hood itself. The oil guiding structure includes an oil collecting trough and a groove that are interconnected. The oil collecting trough is located at the bottom inside the range hood hood, and the groove is in close contact with the outer wall of the range hood hood. The bottom of the groove is not lower than the bottom of the oil collecting trough. A first through hole is provided at the bottom of the oil collecting trough. This utility model uses a groove in close contact with the outer wall of the range hood hood to collect oily liquid condensed and flowing from the outer wall of the range hood hood. The groove and the oil collecting trough are interconnected. The collected oily liquid is discharged outside the machine or into an oil storage container through the groove-oil collecting trough-first through hole. This prevents the oily liquid from dripping or flowing freely along the outer wall of the hood onto the stove surface, cabinets, food, or kitchen utensils without guidance, thus effectively reducing oil pollution, alleviating the subsequent cleaning burden, and eliminating food safety hazards caused by oil dripping.

Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to an oil guiding structure for a range hood and a range hood. Background Technology

[0002] Range hoods are indispensable appliances in modern kitchens. Their main function is to extract cooking fumes, steam, and odors to purify the kitchen air. Their basic working principle involves using a fan system to create a negative pressure zone below the hood, drawing in rising fumes. After passing through filters and other processes such as grease separation, the relatively clean air is discharged outdoors or recycled after secondary treatment. With rising living standards and increasing demand for healthy cooking environments, range hoods have become widely used globally, becoming a core device for improving kitchen environments, and market demand continues to expand.

[0003] However, most existing range hoods have significant shortcomings in the collection and removal of grease. Firstly, there is often a lack of dedicated and effective collection structures for the oily liquid that condenses on the inner and outer walls of the hood, especially on the front and side walls directly facing the heat source of the stove and subjected to direct impact from grease and steam. This grease adhering to the outer walls naturally flows downwards due to gravity, but existing oil-guiding structures typically focus on the bottom oil-collecting area inside the hood. The oily liquid flowing along the outer walls of the hood, especially on the outer walls directly facing the stove and the area directly exposed to grease and steam, is easily overlooked or not collected thoroughly. This can lead to the oily liquid dripping onto the stove and cabinet surfaces, causing contamination, increasing the cleaning burden, and even potentially spilling into food or kitchen utensils, resulting in food safety issues.

[0004] Therefore, there is an urgent need to design an oil guiding structure and a range hood to more effectively collect the oily liquid condensed on the outer wall of the hood. Summary of the Invention

[0005] The purpose of this utility model is to provide an oil guiding structure and a range hood, which solves the problem that the oily liquid condensed and flowing on the outer wall of the range hood is ignored or not collected completely.

[0006] To achieve this objective, the present invention adopts the following technical solution: An oil guiding structure for a range hood includes an oil collecting trough and a groove that are interconnected. The oil collecting trough is located at the bottom inside the range hood hood, and the groove is in close contact with the outer wall of the range hood hood. The bottom of the groove is not lower than the bottom of the oil collecting trough. A first through hole is provided at the bottom of the oil collecting trough.

[0007] Furthermore, it also includes a connecting groove located at the bottom of the range hood hood, wherein the oil collection groove, the connecting groove, and the trench are connected in sequence, and the bottom of the connecting groove is not lower than the bottom of the oil collection groove and the bottom of the connecting groove is not higher than the bottom of the trench.

[0008] Furthermore, the oil collecting trough and the connecting trough are connected by an oil hole, one end of which faces the bottom of the connecting trough; The connecting groove and the trench are connected by a second through hole, one end of which faces the bottom of the trench.

[0009] Furthermore, multiple oil holes are provided between the oil collecting groove and the connecting groove; A connecting pipe is fixed in the second through hole between the connecting groove and the trench, and the second through hole and the connecting pipe are sealed together. The two ends of the connecting pipe are respectively connected to the connecting groove and the trench.

[0010] Furthermore, the bottoms of the oil collecting trough, the connecting trough, and the trench are on the same horizontal plane; An isolation plate is provided between the oil collection tank and the connecting tank.

[0011] Furthermore, several grooves are provided, each located on the outer wall of a different range hood hood, and the grooves at different locations are all connected.

[0012] Furthermore, a support plate is provided between adjacent trenches, and an oil passage is provided on the support plate.

[0013] Furthermore, the first through hole is connected to the oil drain pipe below, and the oil drain pipe extends downward through the range hood hood; or An oil pocket is provided below the first through hole, and the oil pocket is detachably connected to the range hood hood.

[0014] Furthermore, the oil bag is removably mounted below the range hood hood; a handle is provided at one end of the oil bag.

[0015] A range hood includes the range hood oil guiding structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention incorporates a groove that fits tightly against the outer wall of the range hood to collect condensed oily liquid. The groove is interconnected with an oil collection trough. The collected oily liquid is discharged outside the machine or collected in an oil storage container via the groove-oil collection trough-first through hole. This design prevents the oily liquid from dripping or flowing freely along the outer wall of the range hood onto the stove surface, cabinets, food, or kitchen utensils without guidance, effectively reducing oil pollution, alleviating the subsequent cleaning burden, and eliminating food safety hazards caused by dripping oil.

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1: This embodiment provides an oil-guiding structure for a range hood, used to efficiently collect the oily liquid condensed on the outer wall of the range hood 11 from cooking fumes and guide it smoothly out, preventing oily liquid from dripping and causing pollution. Combined with... Figures 1-7As shown, the oil guiding structure of the range hood includes an oil collecting trough 1, a connecting trough 2, and a groove 3 connected in sequence. The groove 3 is closely attached to the outer wall of the range hood hood 11 and is used to collect oily liquid flowing down the outer wall of the range hood hood 11. The connecting trough 2 is located at the bottom inside the range hood hood 11. The connecting trough 2 serves as an intermediate guiding channel, used to receive the oily liquid in the groove 3 and redirect it to the oil collecting trough 1. The oil collecting trough 1 is located at the bottom inside the range hood hood 11 and is used to collect the oily liquid from the connecting trough 2. Of course, the oil collecting trough 1 also collects oil flow from the inner surface of the hood. The bottom of the connecting trough 2 is not lower than the bottom of the oil collecting trough 1, and the bottom of the connecting trough 2 is not higher than the bottom of the groove 3. Therefore, the bottom of the groove 3 is not lower than the bottom of the oil collecting trough 1, ensuring that the oily liquid can flow smoothly from high to low relying solely on gravity, flowing from the groove 3 through the connecting trough 2 and finally converging into the oil collecting trough 1, forming a continuous gravity guiding path. In this embodiment, the bottoms of the oil collecting trough 1, the connecting trough 2, and the trench 3 are on the same horizontal plane. The bottom of the oil collecting trough 1 is provided with a first through hole 4, which is used to discharge all collected oily liquid outside the machine or connect it to an oil storage container. When oily liquid is collected in the oil collecting trough 1, it can be discharged outside the machine or connected to an oil storage container through the first through hole 4. When the amount of oily liquid collected in the trench 3 is greater than the amount of oily liquid in the oil collecting trough 1, under the action of the oily liquid's own gravitational potential energy, the oily liquid in the trench 3 will flow through the connecting trough 2 and then into the oil collecting trough 1, and finally be discharged from the first through hole 4. The first through hole 4 is connected to the oil drain pipe 13 below, and the oil drain pipe 13 extends downwards through the range hood hood 11, allowing the oily liquid collected in the oil collecting trough 1 to flow smoothly downwards through the oil drain pipe 13 to the outside of the machine or to an external container, completing the final discharge process.

[0028] The oil collecting trough 1 and the connecting trough 2 are connected by oil holes 5, one end of which faces the bottom of the connecting trough 2 to reduce oil residue at the bottom of the connecting trough 2. Multiple oil holes 5 are provided between the oil collecting trough 1 and the connecting trough 2 to increase the flow rate of oily liquid, improve oil guiding efficiency, and prevent single-hole blockage from interrupting oil guiding. A partition plate 8 is provided between the oil collecting trough 1 and the connecting trough 2. This serves two purposes: firstly, it separates and fixes the space, facilitating independent manufacturing and installation of the oil collecting trough 1 and the connecting trough 2; secondly, the area above the partition plate 8 provides a stable and reliable structural support surface, particularly suitable for installing and fixing components such as the fume filter 12. The oil holes 5 are located on the partition plate 8.

[0029] The connecting groove 2 and the trench 3 are connected by a second through hole 6, one end of which faces the bottom of the trench 3 to reduce oil residue at the bottom of the trench 3. A connecting pipe 7 is fixed inside the second through hole 6 between the connecting groove 2 and the trench 3, and the connecting pipe 7 is sealed to the second through hole 6. Both ends of the connecting pipe 7 are connected to the connecting groove 2 and the trench 3 respectively. The connecting pipe 7 seals the connection between the connecting groove 2 and the trench 3, effectively preventing oil leakage at the interface and avoiding gaps between the connecting groove 2 and the trench 3 that could affect oil drainage. The connecting pipe 7 can directly cross these gaps.

[0030] Several grooves 3 are provided, each located on the outer wall of a different range hood hood 11. The grooves 3 at different locations are interconnected. These interconnected grooves 3 on the outer walls of different range hood hoods 11 form a surrounding oil collection channel, capable of collecting oily liquid flowing down the outer surface of each range hood hood 11, and guiding it in a unified manner. This significantly expands the oil collection range, improves collection efficiency, and prevents oil from dripping or flowing freely onto the outside of the machine and the stovetop without guidance, effectively avoiding cleaning pollution problems. In this embodiment, each range hood hood 11 has a groove 3 on its outer wall, or each range hood hood 11 facing the stovetop has a groove 3 on its outer wall. Figure 3 As shown, a support plate 9 is provided between adjacent trenches 3, and an oil outlet 10 is provided on the support plate 9. The support plate 9 enhances the structural stability, while the oil outlet 10 ensures that the oily liquid between different trenches 3 can flow and merge smoothly.

[0031] The working process of the oil guiding structure of the range hood in this embodiment is as follows: Hot oil fumes and steam generated during cooking rise to the outer wall of the range hood hood 11 and condense, forming an attached oily liquid. This oily liquid flows downwards along the inner wall of the hood and, more importantly, along the outer wall of the range hood hood 11 under the influence of gravity. The oily liquid flowing to the bottom of the outer wall of the range hood hood 11 is collected by the groove 3 set close to the outer wall of the range hood hood 11. The oily liquid in the groove 3 flows into the connecting groove 2 through the connecting pipe 7, and the oily liquid in the connecting groove 2 flows into the oil collection tank 1 through the oil hole 5. At the same time, the oily liquid flowing down the inner wall of the hood also falls directly into the oil collection tank 1. Finally, all the collected oily liquid converges in the oil collection tank 1 and is discharged uniformly through the first through hole 4-oil drain pipe 13, thus achieving efficient and clean oil collection and discharge.

[0032] Example 2: This embodiment provides an oil guiding structure for a range hood, used to efficiently collect the oily liquid condensed on the outer wall of the range hood hood 11 from cooking fumes and guide it smoothly out, preventing the oily liquid from dripping and causing pollution. The difference between this embodiment and Embodiment 1 is that an oil hopper 14 is provided below the first through hole 4, and the oil hopper 14 is detachably connected to the range hood hood 11. The oil hopper 14 is used to receive and temporarily store the oily liquid flowing down from the first through hole 4. After reaching a certain capacity, it is disposed of centrally by the user. This is suitable for situations with heavy oil stains and low water content. Additionally, as an internal component, it helps maintain a clean overall appearance. In this embodiment, the oil hopper 14 is retractable below the range hood hood 11, greatly simplifying the user's cleaning and maintenance process. A handle is provided at one end of the oil hopper 14, allowing the user to pull out or push in the oil hopper 14 directly without tools, thus facilitating the emptying of the collected oily liquid and the cleaning and maintenance of the oil hopper 14 itself.

[0033] Example 3: This embodiment provides a range hood for extracting and treating cooking fumes generated in the kitchen, providing a clean cooking environment. The range hood includes the oil guiding structure described in Embodiment 1 or Embodiment 2. As one of the core functional components of the range hood, the oil guiding structure effectively solves the problem of collecting and discharging oil fume condensate, significantly improving the cleanliness and ease of maintenance of the range hood.

[0034] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
